Description Reid Spencer 2007-04-08 18:56:47 PDT 
Immediately after Chris' change to inline asm to fix bug 1314, this one
started failing:

Fixed:
http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20070402/047032.html

This also fixes another lurking alpha inline asm bug with memory operands.

Thanks,
